When removing the circuit board after the main power is turned on/off, wait for at least two minute 

before starting to remove the circuit board.   

If the circuit board removal is started immediately after turning off the main power, it can result in 

electric shock or damage to the circuit due to residual electric charge. 

Remove the circuit board by following the steps below. To install the circuit board, reverse the removal 

procedure. 

(1)    Release the lock of the cable clamp (large) .(At 4 locations)   
(2)    Disconnect the X-SUS board connector CN23. 
(3)    Disconnect the Y-SUS board connector CN33. 
(4)    Disconnect the ABUSR board connector CN42. 
(5)    Disconnect the ABUSL board connector CN52. 
(6)    Remove the wires (4), (5) from the cable clamp (small) . 
(7)    Disconnect the LOGIC board connector CN6. 
(8)    Disconnect the PSU signal cable from the PSU board connector CN69 side.

(1) 

Remove the 6 types of printed-circuit board (X-SUS, Y-SUS, ABUSL, ABUSR, LOGIC, PSU) 
that are installed in the panel module.   

For the removal procedure, refer to Section 5.2 to 5.7. 

*    Before removing the above 6 types of board, be sure to remove both ends of the single power 

cable (BLU) and those of the five FPC cables (WHT) that are used to connect the circuit 
boards.
